    -Soil health assessment of KVK Amroha
    (SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2020) Chauhan, Nishant; – Kumar, Dr Ashok
    Study on the soil health assessment of KVK Amroha was conducted during 2019-20.Soil samples were collected and brought to the laboratory of Department of soil Science and Agricultural Chemistry , SVPUAT, Meerut. Results of study indicate that the texture of farm soil was sandy loam. Soils are neutral in nature with very low EC and poor OC (%). Perusal of data also indicates that infiltration rate and hydraulic conductivity of farm soil is moderate to moderately rapid with low water stable aggregate. Soils are low in available nitrogen and medium in phosphorus and potassium. The Ca/Mg ratio of 80 % of farm soil was favorable while ratio of remaining 20 % soil was below favorable .Ratio of Mg/K was within favorable limits. Iron, manganese, copper and zinc were found in sufficient to more than sufficient range. A significant and negative correlation of pH with clay (r = - 0.208), porosity (r = -0.093), IR (r = -0.315), HC (r = -0.315) was found .Similarly OC was significantly and negatively correlated with sand (r = -0.56), porosity (r = - 0.28) but non significantly and negatively with BD(r=-0.355). Physical properties of the soils of study area were not ideal for growing crop satisfactorily. Most of the soils were susceptible to erosion as they have silt / clay ratio, clay ratio, modified clay ratio more than the threshold value (>0.4, 3.44 and 6.9, respectively) and critical level of soil organic matter and clay Moisture equivalent ratio below the threshold value (<3.34 and <1.5, respectively). Based on the study of characterization of soil and fertility status, the soils of study area were found poor in soil health with several limitations and needs special managements to improve soil health and crop production.

    (SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2020) : Singh, Maharaj; : Singh, Maharaj; : Singh, Maharaj; : Singh, Maharaj; : Shahi, Dr. U. P.; : Shahi, Dr. U. P.; : Shahi, Dr. U. P.; : Shahi, Dr. U. P.
    The investigation entitled “Effect of Different Moisture Conservation Techniques on Nutrient Availability, Water Use Efficiency and Productivity of Wheat (Triticum aestivum)”was carried out at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U.P. during Rabi season of 2018-19. The experiment was laid out in a split plot design considering the irrigation levels as main plot and moisture conservation techniques as sub plot treatments with three replications. The irrigation levels consisted of I1– (5 irrigations at CRI, tillering, booting, milking and dough stage), I2– (3 irrigation at CRI, tillering and booting stage), I3– (2 irrigation at CRI and booting stage) and moisture conservation techniques consisted M1 – Control (no moisture conservation techniques), M2 - Rice residues @ 5 ton ha-1), M3 - application of Pusa hydrogel (3kg /Acre), M4- seed treatment with Pseudomonas fluorescens (PF6) @ 4 g kg-1 seed, M5- Seed treatment with Pseudomonas fluorescens (PF2) @ 4 g kg-1 seed and M6- Seed treatment with (IRRI-1) @ 4 g kg-1 seed. The soil of the experimental site was sandy loam in texture, low in available nitrogen and organic carbon, medium in available phosphorus, potassium, zinc and alkaline in reaction. Wheat variety HD-2967 was grown as a test crop. Treatments effect was evaluated in term of plant growth parameters, yield and yield attributed and nutrient content and uptake, nutrient availability in soil and water use efficiency and field water use efficiency of crop. Result reveal that plant height, dry matter accumulation increased with I1 (5 irrigation) and I2 (3 irrigation). Among the yield attributes number of grains per spike, spike length (cm), numbers of spikelet per spike and test weight increased significantly in I1 (5 irrigation), respectively. The improvement in grain yield 8.74 and 17.38 % over I2 and I3 respectively was due to maximum supply of water under I1 (5 irrigation). Among the moisture conservation techniques, the higher plant height and dry matter accumulation was recorded with the application of rice residue incorporate @ 5 ton ha-1. Similarly yield attributes. NPK content and uptake, water use efficiency, were significantly higher with rice residues @ 5 ton ha-1 followed by pusa hydrogel. In combination of the treatment I1M2 (5 irrigations with rice residues @ 5 ton ha-1) was recorded higher grain yield over rest of treatments. The maximum water use efficiency was recorded in the treatment combination I3M2 (2irrigation with rice residues @ 5 ton ha-1). Irrigation treatments combination with M2 (rice residues @ 5 ton ha-1) had higher water use efficiency. Maximum gross return was observed in treatment combination I1M2 (5irrigation with rice residues@ 5 ton ha-1). Among treatments, maximum net return and B: C ratio was recorded under I1M2 (Five irrigation with rice residues @ 5 ton ha-1. Among the microbial inoculate PF-6 was found better in respect & all parameters.

    (SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2020) Pal, Ram; Kumar, Dr. Yogesh
    A field experiment was conducted to assess effect of tillage practices application and performance of rice at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.), during kharif season of 2019. The ten treatments consistency application of tillage practices viz., Conventional puddled transplanted rice, Cultivator ploughing without puddled transplanted, Cultivator ploughing with puddled transplanted, Deep ploughing without puddled transplanted, Deep ploughing with puddled transplanted, Rotavator till without puddled transplanted, Rotavator till with puddled transplanted, Disc plough without puddled transplanted, Disc plough with puddled transplanted and Zero till transplanted rice were tested in RBD with three replications. Pusa Basmati-1 was grown as a test variety. The results revealed that the combine application of tillage practices exhibited significant influence on the growth, yield attributes and yields of rice as compared to zero till transplanted rice during year of experimentation. Significant improvement in growth parameters viz. plant height, number of tillers (m-2), dry matter accumulation (g m-2), yield attributes, protein content, 1000-grain weight, nutrient content and grain yield was recorded with the application of RDF Cultivator ploughing with puddled transplanted, which established its superiority over rest of the tillage practices treatments. The total nitrogen, phosphorus and potassium uptake by rice crop was also highest (60.50, 19.56 and 17.74 kg ha-1), respectively with the application of Cultivator ploughing with puddled transplanted 66.26 and 52.81 per cent increase in grains and straw yield of rice as compare to zero till transplanted rice. The application of Cultivator ploughing with puddled transplanted resulted in to higher protein yield (378.02 kg ha-1). Thus the application of Cultivator ploughing with puddled transplanted found better for sustainability of rice crop yield, respectively.

    (SARDAR VALLABHBHAI PATEL UNIVERSITY OF AGRICULTURE & TECHNOLOGY, MEERUT, 2018) Kumar, Harshit; Dhyani, B.P.
    A field experiment was conducted during rabi season 2017-18 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Ten different treatments viz, control (without NPK), T2 100% NPK, T3 100% NPK + Zn @ 2.5 kgha-1, T4 100% NPK + Zn@5.0 kgha-1,T5 100% NPK+ vermicompost @ 1.0 tonha-1 ,T6 100%NPK +Zn 2.5 kgha-1 + vermicompost@100 tonha-1,T7 100% NPK+Zn@5.0 kgha-1 + vermicompost@1.0 tonha-1.T8 100%NPK + vermicompost @ 2tonha-1 ,T9 100%NPK + Zn @2.5 kgha-1 + vermicompost and T10 100%NPK +Zn@5.0kg ha-1 + vermicompost@2.0 ton ha-1 were tested in a randomized block design with three replications. Soil of experimental site was sandy loam in texture, alkaline in reaction, low in available nitrogen, organic nitrogen, medium in available phosphorus, potassium and zinc. Late sown wheat variety PBW 590 was grown as a test crop. With exception of zinc and vermicompost application common package and practices of wheat agronomy was followed in all treatments. Treatments effect was evaluated in term of plant growth, yield attributed and yield, nutrient content and uptake and nutrient availability in soil. Results reveal that plant growth, parameters improve with application of zinc or vermicompost over 100% NPK although improvement in plant height with application of zinc was non significant. Conjoint application of zinc and vermicompost over 100% NPK resulted in a significant improvement in yield attributed. Grain and straw yield increased significantly with the application of either level of zinc or vermicompost over 100% NPK. Conjoint application of zinc and vermicompost improve the yield further and significantly higher yield was recorded with the application of 2 ton ha-1 vermicompost over 100% NPK + Zn @2.5 kgha-1 or 100%NPK +Zn @5 kgha-1. Plant nutrient content and uptake differ significantly with the application of different treatments. Nutrient availability in soil differ significantly under the influence of different treatments. With exception of phosphorus nutrient availability decline with crop growth advancement. Application of vermicompost resulted in higher organic carbon in soil. Treatments consisting application of 100% NPK + Zn @ 5 kg ha-1 + vermicompost @ 2 ton ha-1 was found most remunerative although B:C ratio was higher in T4. From experiment it may be concluded that the application of zinc or vermicompostover the recommended NPK level is better practices to augment wheat yield. Conjoint application of these two will further improve the yield.

    Nitrogen Management for Late Sown Wheat (Triticum aestivum L.) Crop
    (SARDAR VALLABHBHAI PATEL UNIVERSITY OF AGRICULTURE & TECHNOLOGY, MEERUT, 2018) KUMAR, VIPIN; Dhyani, B.P.
    A field experiment was conducted during rabi season 2016-17 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to evaluate the nitrogen management for late sown wheat (Triticum aestivum L.) crop. The area situated at a latitude of 29o 40′ North and longitude of 77o 42′ East with an elevation of 237 m above mean sea level. The soil of the experimental field was well drained, sandy loam in texture, alkaline in reaction (pH 7.80), low in available nitrogen, medium in available phosphorus and potassium with an electrical conductivity 0.25 dS m-1 . Eleven treatments comprising Control, RDN for timely as well as late sown wheat with different application schedule were tested in RBD with three replications. The crop was grown with the recommended package and practices for wheat with exception of nitrogen application which was variable. The data on growth, yield and its contributing traits content and uptake of nutrients at various stages along with available N, P, K in soil were estimated as per the standard procedure. The experimental results revealed that growth attributes (plant height, number of tillers, dry matter), yield attributing traits viz., Number of spikelet spike-1 , spike length, number of grains spike-1 , test weight and biological yield, grain yield, straw yield and uptake of nitrogen, phosphorus and potassium in wheat differ significantly among different treatments. Growth parameters were significantly better in the treatments where major portion of N was applied during early growth period. The highest grain yield and harvest index was recorded in T8 where 60% of recommended N in accordance to timely sown wheat was applied at sowing. This treatment was found statistically similar to T4, T6 and T10. Growth and yield attributing character were comparatively higher in T8. Available nutrient in soil after harvest of wheat were variable under different treatments. From the study it may be concluded that application of nitrogen in accordance to late sown wheat recommendation is not sufficient and it should be increased. The effect of N application schedule on performance of late sown wheat was observed only with the nitrogen application on the basis of timely sown condition while no significant effect was observed in case of late sown condition.
